 * In order to create a fragmented connect using the connect request above:
 * 1) Copy the connect request to both fragments.
 * 2) Strip away the ETH header, the IP header and the UDP header (0x2a bytes) from both packets (already done!!!)
 * 3) In fragment 1 change byte [0x2c] from 0x28 to 0x2c.   (means fragment)
 * 4) In fragment 2 change byte [0x2c] from 0x28 to 0x2e.   (means last fragment)
 * 5) Modify fragment length member of both frames:
 *    a) Fragment 1: bytes [0x74..0x75] from {0x86 0x01} to [0x00 0x01] (means 0x100 bytes).
 *    b) Fragment 2: bytes [0x74..0x75] from {0x86 0x01} to [0x86 0x00] (means 0x86  bytes).
